BURNER AND MIXER FOR CAUTERY.

SPECIFICATION forming part of Letters Patent No. 767,231, dated August 9, 1904,

Application filed June 3, 1904. Serial No, 210,977. iNo model.)

To rt/Z wwnt it ntcty/ con/007%:

Be it known that I, JOHN P. MLLER, a citizen of the United States, and a resident of the city of New Yorlnborough of Manhattan, in the county and State of New York, have invented a new and Improved Burner and Mixer for Cautery, of which the following is afull, clear, and exact description.

The object of the invention is to provide a new and improved burner and mixer for cautery and arranged to provide a burner for the initial exterior heating of the cauterizing-tool and a mixing-chamber having the same source of gas-supply as the burner and arranged to permit minute regulation of the amount of gas and air required to furnish a proper mixture to be burned in the cauteriZing-tool.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a perspective view of the improvement. Fig. 2 is an enlarged sectional side elevation of the improvement, and Fig. 3

is a cross-section of the saine on the line 3 3' of Fig. 2.

A suitably-constructed casing A is mounted on a stand B and is provided with a port a, connected with a nipple O, engaged by one end of a flexible tube D, connected at its other end with a gas-jet or other suitable source of gas-supply E, vas plainly indicated in Fig. 1. From the port a extendsupwardly a port b, leading to a Bunsen burner, comprising the nozzle F and a tube F, inclosing the said noz- Zle and having air-inlets F2 near the lower end, as plainly indicated in the drawings. The amount of gas passing through the Bunsen burner by way of the port a and the port bis regulated by a suitable valve-plug G, extending into the port and provided at its outer end with a handle G under the control of the operator for turning the valve-plug G to allow more or less gas to pass from the port a through the port into the Bunsen burner. On the valve-plug G is secured an arm G2, adapted to abut against the stop-pins G3 G4, held on the casing A, to indicate the position ofthe valveplug Gthat is, when the arm G2 abuts against the stop-pin G3 then the port L is completely open and when the handle G' is turned and the arm G2 abuts against the stop-pin Gt then the gas is completely shut off from the Bunsen burner.

.The port ce leads to the lower end of a valvechamber H, containing a valve I, having its lower end I' made conical and normally seated on a correspondingly-shaped seat in the bottom of the chamber H. The port a leads to the conical portion of the seat, and a port c connected with the atmospheric air alsoleads to the said conical seat directly opposite the port a. Through the center ofthe valveI extends an opening' I2, so that when the valve I is lifted off its seat then gas from the port a and air from the port c can pass into the conical portion of the valve-seat and then to the opening I2 and through the same to pass into the upper end of the valve-chamber H. The upper end of the valve-chamber H is provided with a nipple J, connected with one end of a flexible tube K, leading to a pressure-bulb L of the usual construction and discharging' into a pressure-reservoir N, connected by a iiexible tube K with the canteriZing-tool O, having a suitable handle P to permit the user to conveniently manipulate the cauteriZing-tool. The valve I is normally held to its seat by its own weight and by the pressure of a spring Qpressing with its lower end on the top of the valve I yand engaged at its upper end by a screw-cap R, screwing in the upper end of the valve-chamber I-I. Now by the operator turning the screw-cap R either inward or outward the tension of they spring Q can be increased or diminished to hold the valve I with more or less force on its seat.

In order to regulate the amount of gas passing through the lport o into the conical portion of the valve-seat for the valve I, a regulating device is provided in the form of a screw screwing transversely in the casing A into the port a to allow more or less gas to flow through the port a into the conical seat.

IOO

.ein t@ The screw S is located between the valve-seat and the port so that the screw S does not influence in the least the'iiow of gas from the port a to the port7/and to the Bunsen burner.

rIhe operation is as follows: Then the several parts are in the positions illustrated in Figs. l and 2 and the gas is turned on from the gas-supply E, the valve Gr opened, and the Bunsen burner is lighted, then the cauterizing-tool O by being' held in the flame of the Bunsen burner becomes readily heated to the desired deg'ree. When this has been done, then the operator can close the valve-plug Gr and alternately press and release the bulb L, so as to create a vacuum in the upper portion of the valve-chamber H to lift the valvel ofI' its seat, whereby gas can now pass fro'm the port uf and air Jfrom the port o into the lower end of the chamber H to cause the mixture of the g'as and air, the mixture passing up through the opening I2 into the upper end of the valve-chamber H and from the latter by way of the nipple J and tube K into the bulb L, from which the mixture of gas and air is forced into the reservoir N and through the pipe or tube K into the tool O, in which the gas is now burned by coming in contact with the highly-heated tool O.

From the foregoing it will be seen that the supply of gas to the Bunsen burner for the preliminary heating' of the cauterizingtool O is not in the least interfered with by the mixing' apparatus for furnishing the combustible mixture of gas and air for the interior of the cauteriZing-tool to keep the latter at the proper heat during use. By having the valve-plug G arranged as described the supply of gas to the Bunsen burner can be shut off as soon as the preliminary heating' of the cauterizingtool O has been accomplished. It will also be seen by having the regulating device S in the port L any desired amount of gas can be mixed with the air to produce a proper inlam mable mixture to insure the uniform heating of the cauteriZing-tool O, and by adjusting the screw-cap R the valve I is held with more or less force to its seat, according to the pressure in the gas-supply.

Having thus described my invention, I claim as new and desire to secure by Letters PatentW 1. A burner and mixer for cautery, provided with a valve-chamber having an outlet and connected with a gas-supply and an airsupply below the outlet and having a central opening, a valve in the said chamber normally closing the connection with the gassupply and the air-supply, a cauterizing-tool, a flexible connection between the tool and the said outlet, and a pressure-bulb in the said iiexible connection to createa suction in the said valve-chamber to lift the valve off its seat to connect the gas-supply and the air-supply with the central opening' in the valve.
